A Papular Eruption on the Face: A Distinct Subtype of Lichen Planopilaris?

    March 2013 in “ Journal of Dermatological Case Reports ”

    TLDR A rare skin condition affected only the facial hair of a 46-year-old man.
    The document reported a case of a 46-year-old man with an unusual presentation of lichen planopilaris (LPP), a scarring alopecia typically affecting the scalp. This case was distinct as it involved only the facial vellus hair, presenting as asymptomatic papular eruptions on the face without scalp involvement. Histologic examination confirmed a lymphocytic peri-follicular lichenoid interface dermatitis. The patient had a 30-year history of absent eyebrow hair growth. This presentation was rare, with only a few documented cases, primarily in perimenopausal women with frontal fibrosing alopecia (FFA). Treatment for LPP remains challenging, with no standard protocol, and facial involvement further complicates management.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      Excess sebum rich in cholesterol and triglycerides can lead to hair loss through inflammation, with treatments like Ciclopirox shampoo, Benzoyl Peroxide shampoo, and Clindamycin gel recommended for managing conditions like seborrheic dermatitis and folliculitis. Pioglitazone is suggested for Lichen Planopilaris, while Omega-3s and reducing processed foods may improve sebum quality, though genetic factors play a significant role.

      Men with hair loss might have lichen planopilaris (LPP), which can mimic androgenetic alopecia, leading to misdiagnosis and ineffective treatment with finasteride or dutasteride. Proper diagnosis, including biopsies, is crucial to distinguish between androgenetic alopecia and conditions like LPP.
